o HANGEAsLE-sPEaD G EARING.'

To all whom it may concern/.1

Be it known that I, ELLIS BURR, a citizen of the United States, residing at Champaign, in the county of Champaign and-State inois, have invented certain new and useful, Im rovements in Changeable-Speed Gearing, o which the following 1s a specifica-` tain speed.

inventionis embodied in a structurev for t e purpose described that is exceedingly 3 simple and efficient i'n operation as well as 1nex ensiveto construct.

.I have shown the gearing and the operating-lever andl connections mounted in the frame of an automobile which frame is shown as rectangular and made up of the side pieces and 11 and the front and rear end, pieces 12 and 13. These.' ieces are secured together in any desirel manner and suitably raced, as shown. Where the invention is used in an automobile, the power is preferably applied first to the ily-wheel shaft 14, which 1s shown as journale versal joint 18 connects the inner end of this irlsuitable bearlings and 16, formed in or secured'upon the .end piece 12 and thel cross-.piece 17. A uniy shaft to an intermediate section'. 19 'of the driving-shaft, the other endv of which is' connected by the universal joint 20 to the rear section 21 ofthedriving-shaft. This rearv sectiony 21, as best Shown in 3 and'4, has an clon ated bearing-sleeve 22, the rear'end of whici is secured in thel collar 23 ofthe yoke 24, the yoke 24` having `the two arms 25 ofthe fork,- Whichare preferably circular` in cross-section and which are adapted .to slide 'back and forth inthe similarlyeshaped. a ertures formed in the bearing-blocks 26,- w ch fare' ivotally secured in the side ieces of the .U- aped frame 27, the rear en of which" is secured to the innerv side ofthe rear wall of and '30' for .the rear axle 31. I have shown this rear axle as continuous for convenience of illustration; but itwill be understood that '.theframe 28,-wl1ich carries the bearings 29 it may beA divided and provided'with the cus- 'tomaryequalizing-gear,which is intended to be mountedf'in the space 32, formed in the frame 28 on that portion of the shaft which is shown as surrounded by the collar 33.

Ihave illustrated the bearings 29 and v3() my invention. The .shaft or axle 31 has secured thereon the loppositely-facing bevel gear-wheels 35 and 36, which are preferably secured to the hub which in turn is secured to the shaft 31.

The-rear section 21- of the drivin -shaft has secured 4thereonto rotate therewit thethree bevel gear-pinions38, 39, and 40, the pinion' "40 beingthe largest and used for the highest speed, t Ve pinion` 39 being intermediate and used, for intermediate speed,- and the p1n1on Y'38?being the smallest and'sed' for the slow speed `being adapted *to` engage wi'th, v

`Jas 'being provided with the -rollers 34; but it i fwill'be understood that they form no part of IIO IVO

either the gear-wheel 35 for forward move- 62 will be rocked. The shaft` 62 is preferably nient or with the gear-wheel 36 for backward 1 supported intermediate the end bearings by movi-mentl I might arrange-the other pinions` 39 and 40 so as to engage with either wheel, if desired; but as only the slow s eed is needed for backing' an automobile I fiave shown only the pinion 38 as arranged to engage with the wheel 36. For convenience of construction I have shown the pinion 38 as cut on the end of the sleeve 41, which surrounds a portion of the bearing-sleeve 22 and` which is secured to the shaft 21 by the spline 42. The bevel-pinions 39 and 40 are secured on the sleeve 41, and the thrust-bearing for the bearing-sleeve 43, in which the sleeve 41 is journaled,y is formed by the antifrictionballs 44, mounted in the customary collar 45, which is placed between the bearing-surface on the base of the pinion 4() and the bearing-surface formed on the flange 46, forming the inner end of the bearing-sleeve 43.

To securely hold the pinion 38 39, or 40, as the case may be, in mesh with the wheel 35 or 36, as the case may be, I provide one or mort.` plates 47 and 48, a top and bottom plate being shown, as seen in section in Fig. 4.

These plates are secured to the forward portion of the frame 28 and have the ends of the frame 27 secured thereto, as shown in Fig. 4., These plates 47 and 48 havev the recessed slots 49 formed therein and consisting of the slow-speed Jforward notch 50, the slow-speed rearward notch 51, themedim-s eed forward notch 52; and the high-spec forward notch 53, these notches being connected by the straight passa e 54 and the notches 50, 51, and 52 being e ongated and on the arc of a circle whose center is the axis of the pivoted bearings 26. The bearing-sleeve 43 has the bosses 55 and 56 projecting downwardly and upwardly therefrom and whose top and bottom surfaces engage with the adjacent surfaces of the plates 47 and 48. Guiding-pins 57 and 58 are secured in .these bosses 55 and 56'and pass through the recessed apertures 49, so t at the pinions 3,8, 39,- and 40 will be properly guided in bringing them into and out of engagement.

Vhere the invention is to be used with automobiles, it is necessary to provide some means for changing the gearing adjacent the drivers seat, and for this purpose I employ the hand-lever 59,' which is pivotally mounted by the pin 60 on the flattened end 61 ofthe rock-shaft 62, which is journaled in suitable bearings carried by the side pieces 1() and 11 and held from longitudinal movement therein by the collars 63 and 64, se-

cured thereon` justhinside ofthe bearings. The lever 59 has the elon ated slot 65 formed therein, through which le flattened end 61 of the rock-shaft 62 passes, and it will be a parent that when'the lever is rocked in t e direction of the length of the vehicle the shaft l l i .of and a bearing formed in the bracket 66, and secured to the shaft adjacent this bracket 66 is the crank-arm 67, to the outer end of which is ivoted the link 68, whose rear end is pivotally connected to the bell-crank 69, which is pivoted on the cross-piece 7 0 of the frame. The longitudinal arm of the bellcrank 69 is much longer than the transverse arm and has the elongated slot- 71 formed in the end thereof, and through this slot 71 passes the bolt 72, which is secured at its upper and `lower endsto the left-hand ends of the shifting levers 73 and 74, the upper .lever 73 being ivotally mounted on the pin 58, while the ower lever 74 is pivotally mounted on the in 57, both levers being just outside caring on their respective plates 48 and 47. -The right-hand ends of these floating levers 73 and 74 are connected by the pin or bolt 75, which has pivoted thereon the link 76, the forward end of which is pivoted on the transverse arm of the bell-crank 77, fulcrumed on the cross-piece 78. The other arm of the bell-crank 77 has the link 7 9 pivoted thereto, the other end of which is pivoted tothe lower end of the lever 59. By an examination of Figs. 1 and 2 it will be seen that when the leverl 59 is swung in a plane longitudinall of the frame it will, through the rock-shaft 62, bell-crank 69, and connections, move the levers 73 and 74 transversely of the frame, whereas when the lever 59 is swung transversely of the frame it will, through the bell-crank 77 and the link' connections, move the levers 73 and 74 longitudinally ofthe frame. 'By thev combined movement-s of the lever 59 it will be apparent that the levers 73 and 74 can be shifted intov an necessary positions to bring the pins eit er into the notch 53, in which the vehicle moves forward at full speed, in the notch 52, in which the vehicle moves forward at rnedium speed, in the notch 50, in which it moves forward at slow speed, or in,the notch 51, in whichit moves backward at slow speed. The movements in the two directions are combined, as it were, and guided by the slots of the recessed plate 8,0, which is curved, as shown in Fig. 6,v and is secured by the brackets 81 and 82 upon the side piece 11 of the frame. `.The plate 8() is provided with the recess or notch 83, correspon-fling to the notch 53, the notch 84, corresponding 'to the notch 52, the notch 85, corresponding to the notch 50, andthe notch 86, corresponding vto the notch 51, and these notches are connected by'a passage through which the -adjacent portion of the lever'59 moves. By means of the connections here shown and' the two guidingplates with their notches I am enabled by the moving of the lever and 7 4's0 as to bring the pinions into any desired engagement to secure the desired speed.

59 to move the levers 73 l preferably .arrange to lock the pinionsy in engagement in connection with the plates 47 and 48, as Well asl through the medium of the lever59, being locked by means of thespringpressed lug 87 engaging the apertures 88, 89, and 90 adjacent. the recesses 83, 8.4, and 85. The lug 87 is formed on the outer end of the yoke-shaped lever- 91, which embraces the lever 59 and is ivoted at 92 topa. collar 93., securedv on sai lever. A link 94, pivoted to the lever 91, extendsu Ward along thelever 59 tothe .handle-95, w 'ch embraces the upper end of the lever 5 9 and is pivoted thereto at 96. v- A' helically-coiled expandin -s ring 97, secured in the tubeconstituting t e ody of the lever.59,-l presses down on1the upper' vside of the pin-98, extending across the yoke ofthe lever 91, and througha slot 99,- formed .in the .handle 59'. The action ofthe spring on the lever 91, thus-,serves'to hold the lug 87 in engagement with whichever aperture is ady jacent to the notchin the plate 80, in which the lever 59 isset. 'This mechanism locks the lever, and .itcan be--released, as-will be apparent, by pressing thehandle 95 toward t e lever 59. 4The in 98 has secured thereto the link 100,* wh1ch extends downwardly f through the inside ofthe' tube. constituting the body of the lever 59 and is pivoted to the .horizontal arm of the bell-crank 1101, which is pivoted to the lug 1021, formed o n the side of the lever 59. Thevertical arm'of the bell- I cranklOl iso'ffset, as seen at1'03, so'that the `link 104, piyoted to theouter end thereof, is

whichis pivoted on..the bracket 106, pro-5 jecting inwardly-:fromthesidepiece 10. The transverse arm of .the'bellcrank 105 has the link 107 pivoted. thereto, andthislnk .exi tends rearwardl 'and-is ivoted to the verti. cal arm of a bel crank ever 108, fulcrumed on a bracket. secured tothe frame' 28, the
